I am in charge of Postgraduate Admissions. I have previously been in charge of Undergraduate Admissions, Examinations and Timetabling. I have served on the Departmental Board, the Course Committee, the Library Committee, the Staff-Student Panel, and the Computing Committee.
I obtained my first degree from Oxford University in 1968, and my PhD from Manchester University in 1972. I was a Royal Society Postdoctoral Fellow in Leiden in the Netherlands from 1972 to 1974, before being appointed to a lectureship at Cardiff University in 1974. I was awarded a personal chair in 2000.

Anrhydeddau a Dyfarniadau

I have been invited to present papers at many international conferences, including `IAU Symposium 237: Triggered Star Formation in a Turbulent IsM' in Prague in 2006; `Protostars and Planets V' in Hawai'i in 2005; `The Young Local Universe' in Aosta in 2004;`Cores to clusters: star formation with next generation telescopes' in Porto in 2004, `IAU Symposium 208: Astrophysical Supercomputing using particle simulations' in Tokyo in 2001; and `From darkness to light: the origin of young star clusters' in Corsica in 2001. I have served on several research committees, panels etc., including the European Commission Physics Panel, the PPARC Astronomy Theory Sub Panel, the HECToR Science Committee, and the UKAFF TAC. I have been Visiting Professor at the Ecole Normale Superieure in Paris.

1974

I teach a 1st-year course on `Mathematical Physics', a 3rd-year course on `Stellar Structure', a 4th-year course on `The Interstellar Medium and Star Formation', and a postgraduate course on `Star Formation'.. I give tutorials to 1st- and 2nd-year undergraduates, and supervise 3rd- and 4th-year undergraduate projects.

Research interests

My main research interest is the theory of the formation of stars, brown dwarfs and planets, in particular the roles played by impulsive dynamical processes, magnetic fields, thermal physics, radiation transport and feedback, in determining the masses, clustering and binary properties of stars. I make extensive use of computer simulations, combined with other theoretical and statistical tools, and I enjoy close collaborations with the observers in the School. I am also interested in stellar evolution, interstellar matter, and galactic structure.
